Expert Determination                   

EMS are Accredited Expert Determiners

Expert Determination (ED) is a dispute resolution process (ADR) in which an independent expert in the subject matter of the dispute, is appointed by the parties to resolve the matter.

As the name suggests is is carried out by an expert in the subject matter rather than by a judge or lawyer

It is not Arbitration,  Its is not Adjudication, It is not Conciliation, It is not Mediation, It is not Expert Evaluation

Is essentially a contractually based form of dispute resolution. Unlike some forms of dispute resolution it is not governed by statute nor are its origins found in other parts of the world

The expert’s decision is – by prior agreement of the parties – legally binding on the parties. Like all ADR processes it is entirely confidential. Expert determination is ideally suited to contractual matters, disputes and matters of valuation and / or which are primarily dependent on technical issues eg. does the vessel / work match the specification.  Is the malfunction due to design or manufacturing fault.

Expert Determination can also be used in many other areas such as fitness for purpose, sale of goods disputes because of its flexibility.

Expert Determination is ideally suited to multi-party disputes

The Expert’s Determiner’s decision is legally binding. There is only a very limited basis to challenge the determination. It is therefore important that the parties select an expert with both relevant expertise and experience in addition to knowledge of the Determination process

The Academy of Experts standard set of Rules for Expert Determination (2023) being strongly recommended. Similarly you will need to agree the terms of the Expert’s appointment


  • Expert Determination provides Cost Efficient Resolution for disputes and problems
  • Expert Determination is confidential and very private
  • The parties control the procedures to be used
  • The process is quick and a mutually acceptable timetable can be set by the parties
  • Matters are determined by an Expert
  • The outcome is final and (normally) binding , unless otherwise agreed in advance
  • Expert Determination is controlled by the parties, not court or arbitration rules
  • Expert Determination is inexpensive & quick
  • Expert Determination Works

It is simply the law of contract. If two parties agree that the price of the vessel or contract or work done or repairs carried out etc etc, should be fixed by an expert determiner on whom they both agree, and he gives that valuation (decision) honestly and in good faith, the parties are bound by it
